Second-hand tobacco exposure in children: evidence for action
A partir d'une revue systématique de la littérature publiée jusqu'en janvier 2021 (11 études), cette méta-analyse évalue l'effet, sur la santé respiratoire ou l'exposition au tabagisme passif des enfants, des politiques anti-tabac dans les espaces extérieurs ou les lieux privés
Tobacco is one of the leading risk factors for disease burden and death in the world. This burden is related to both tobacco consumption and second-hand exposure. Children are particularly exposed; in 2019, it was estimated that passive smoking was responsible for 50 000 deaths and 4 500 000 disability-adjusted life-years among children younger than 14 years. Over the last two decades, especially following WHO's Framework Convention on Tobacco Control in 2003, comprehensive tobacco control policies (including smoking bans) have been promoted internationally and implemented in many countries worldwide. These policies have proven to be effective in reducing smoking prevalence.2 In addition, these policies are associated with substantial benefits for children's health.3 The burden of second-hand exposure decreased by 80% among children younger than 14 years between 1990 and 2019.
In this context, the question arises of exposures that have received little or no consideration in these national strategies, which are mainly focused on indoor public spaces and workplaces. Such environments include outdoor areas (eg, parks), semi-private places (eg, community buildings), and private places (eg, cars). Numerous national and local initiatives have been implemented to reduce these exposures;4 however, they are still substantial.5, 6 Data on their effectiveness are needed to support their implementation.
